UMO+ Hot End Isolator Tube Stuck in PEEK

Recommended Posts


I was assembling my UMO+, and I realized that I had screwed the hot end isolator tube into the wrong side of the peek, and now I can't unscrew it (I tried wrenches, bare hands, gloves, tried until i got bloody fingers). Does anybody have any tips for this? It's kinda sad, cuz if I can't fix it, I'm kinda screwed (and my local reseller doesn't sell a UMO+ hotend pack).

Thanks in advance!

What I do to take it out its:

Assemble the nozzle while hot like if you where going to use it. Then unscrew the peek. It comes out very easy if the nozzle pressure it's 'on'. I broke 4 barrels or more before finding out :D

Upss I get it. You can't do that... Then do what gr5 says indeed.
